Oracle Tomcat 8080 port conflict in Linux

When tomcat is started, the system prompts that port 8080 is in use. After searching, it finds that the Oracle, tomcat, jboss, and other servers occupying port 8080 are installed on one machine, port 8080 is occupied.

I. first check the usage of port 8080

[Root @ olivenan root] # lsof-I: 8080-n

COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME

Tnslsnr 1031 oracle 12u IPv4 2013 TCP *: webcache (LISTEN)

[Root @ olivenan root] # lsof-I tcp: 8080-n

COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME

Tnslsnr 1031 oracle 12u IPv4 2013 TCP *: webcache (LISTEN)

It is found that port 8080 is used by oracle. Pay attention to the use of lsof command parameters.

[Root @ olivenan root] # lsof-I udp: 8080-n

[Root @ olivenan root] # lsof-I | grep 8080

[Root @ olivenan root] # netstat-tln | grep 8080

Tcp 0 0 0.0.0.0: 8080 0.0.0.0: * LISTEN

[Root @ olivenan root] #

Set *. dispatchers = '(PROTOCOL = TCP) (SERVICE = orclXDB )'

Change to # *. dispatchers = '(PROTOCOL = TCP) (SERVICE = orclXDB )'

Iii. solution 2


Convert the xmlDB port to another port. In this example, convert it to 8082.

SQL> call dbms_xdb.cfg_update (updateXML (dbms_xdb.get _get (), '/xdbconfig/sysconfig/protocolconfig/httpconfig/http-port/text

() ', 8082 ));

Call completed.

SQL> exec dbms_xdb.mongo_refresh;

PL/SQL procedure successfully completed.

Convert an ftp port from 2100 to 2111

SQL> call dbms_xdb.cfg_update (updateXML (dbms_xdb.get _get (), '/xdbconfig/sysconfig/protocolconfig/ftpconfig/ftp-port/text

() ', 2111 ));

Call completed.

SQL> commit;

Commit complete.

SQL> exec dbms_xdb.mongo_refresh;

PL/SQL procedure successfully completed.

SQL>

SQL> select dbms_xdb.get _get from dual;

Pai_get

Check the Conversion Result and find that ports 80 and 8082 are disabled, while ports 2111 and are used.

************************************

Note: The above resolves conflicts with XDB. I found that most people are asking about conflicts with the OSE (oracle servlet engine), which occurs when accessing port 8080, what we see is a stubborn small

Fliggy.

The solution is as follows:

My oracle is installed on the d disk. You can find it based on your situation.

D: oracleora90jisinstall> sess_sh-u sys/change_on_install-role SYSDBA-s jdbc: oracle: oci8: @ oradb (enter your service name here, my name is oradb)

-- Session Shell --

-- Type "help" at the command line for help message

$ @ Serverendp. ssh admin 4321 4322-register

$ Exit

You can replace the original 8080 with 4321, and replace 9090 with 4322.
